Here, down my country Sreten... G can be considered G ay(hahahah) and this class is avoided because no good market for them... alone in the whole life.
Joking , and just o talk a little:

- In 1980 i was very close to to go German to learn some about Bosch Fernsehen television broadcasting equipments, and my teacher learned us that cannot call Gay people in German because this is a big crime over there... this way people used the law article, that order to put in prison the one that offend some people calling this way, was article 157... this way, people used those number to mention those people, unhappy because will live too much alone, probable.

This way class G personal uses to put protude things under motorcicle seats here down in Brazil.. we have some of them, they are clever and interesting...but also too much alone here.
